Application filed February 2, 1921. Serial No. 441,942.

To all to 7mm it may concern:

Be it known that I, HENRY L. MUNsoN, a citizen of the United States, residing at Fort Wayne, in the county of Allen, State of Indiana, have invented certain new and use ful Improvements in -Heating Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention,

'such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in heating devices and particularly to air heaters.

The object or the invention resides in the provision of a stove structure by means of which the hot air, from around the burner, will be passed downwardly around the lower edges of the inner wall of the structure, and upwardly thereover, means being also provided for mixing cooler air therewith.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a side elevationof a heating device made in accordance with the invention.

Fig. 2 is a top plan view of the heating device.

Fig. 3 is a vertical transverse central sectional View taken on the line 33 of Fig. 2.

Fig. 4B is a vertical longitudinal central sectional view taken on the line 4i of Fi 2. p

' eferring particularly to the accompanying drawing, represents the outer shell or casing of the heating device, in the end of the upper wall of which is secured the flue 11, and in the center of which is secured the lower end of the heat conveying coiled pipe 12. The other end of this coil is connected with the flue 11, at a suitable distance above the casing 10. Extending longitudinally within the shell 10, and spaced below the upper wall of the casing, is a horizontal wall 13, forming the crown sheet of the firepot. Secured to the longer side edges of the crown sheet, and extending downwardly and outwardly therefrom, are the side walls 14, the opposite ends of said walls being spaced from the end walls of the casingor shell 10. The lower edges of the side walls 14 are shell, to provide spaces through which heat may pass from the oil burner 15, located between the walls 14, and below the crown 1 sheet 13. In the lower portions of the side walls of the shell or casing are formed the longitudinal rows of air inlet openings 16, said openings being disposed below the lower edges of the walls 14. The said lower edges of the walls 1% are supported by the brackets 17 carried by the inner faces of the side walls of the casing 10. The casing or shell is supported by the legs 18.

In the flue 11, at the upper wall of the shell, is arranged a damper 19, while a similar damper 20 is arranged in the upper portion of the coil 12 at the point of attachment of said coil with the flue. By closing the lower damper 19, and opening the upper damper 20, the heat will pass through the coil 12 and out through the flue, above the said damper 20. By opening both dampers, the heat, and products of combustion will pass'directly upwardly through the flue. I

The heat from the burner will pass upwardly against the crown sheet, and be deflected downwardly by the inclined walls 14, to pass around thelower edges of said walls and thence upwardly between the walls 14 and the side walls of the shell, cold air being drawn in through the openings 16, and mixing with the hot air, as it passes to the coil 12 or to the flue 11.

I wish it understood that the heat radiator is adapted for use with stoves of other types, such as heating stoves, furnaces, and cook stoves.

Disposed transversely through the coiled pipe 12, and also through the portion of the pipe which connects with the flue 11, adjacent the damper 20, and in a horizontal plane, are the small hot air flues or tubes 25, and disposed vertically through the last-named portion of the pipe are the similar flues or tubes 26. Air from the room passing through these flues and 26, will become heated to distribute the same to the air of the room.

What is claimed is:

A heater comprising an outer inclosing shell, a flue connected with the shell, a casing within the shell and consisting of a horizontal upper wall spaced below the upper wall of the shell and downwardly and of the shell supporting the side Walls of the casing. 10

In testimony whereof, I aifix my signature,

in the presence of two witnesses.
